Operating Basics
6. If your CD/DVDs become dusty or dirty, wipe them with a clean dry
cloth. Wipe from the center out, do not wipe in a circular direction
around the CD/DVD. If necessary, use a cloth dampened in water or a
neutral cleaner. Do not use benzine, thinner or similar cleaner.
Floppy disks
1. Store your floppy disks in the container they came in to protect them
and keep them clean. If a floppy disk is dirty, do not use cleaning fluid.
Clean it with a soft damp cloth.
2. Do not slide back the floppy disk’s protective metal covering or touch
the floppy disk’s magnetic surface. Fingerprints may prevent the floppy
disk drive from reading data from the floppy disk.
3. Data may be lost if the floppy disk is twisted; bent; or exposed to direct
sunlight, extreme heat or cold.
4. Do not place heavy objects on your floppy disks.
5. Do not eat, smoke, or use erasers near your floppy disks. Foreign
particles inside the floppy disk’s jacket can damage the magnetic
surface.
6. Magnetic energy can destroy the data on your floppy disks. Keep your
floppy disks away from speakers, radios, television sets and other
sources of magnetic fields.
Sound System
Using the microphone
Your computer has a built-in microphone that can be used to record
monaural sounds into your applications. It can also be used to issue voice
commands to applications that support such functions.
Since your computer has a built-in microphone and speaker, “howling” may
be heard under certain conditions. Howling occurs when sound from the
speaker is picked up in the microphone and amplified back to the speaker,
which amplifies it again to the microphone.
This howling occurs repeatedly and causes a very loud, high-pitched noise.
It is a common phenomenon that occurs in any sound system when the
microphone input is output to the speaker (throughput) and the speaker
volume is too loud or too close to the microphone. You can control
throughput by adjusting the volume of your speaker or through the Mute
function.
To adjust the volume or activate Mute, click start, point to All Programs,
point to Accessories, point to Entertainment and click Volume Control.
In the Volume Control panel, you can use the slide bars to adjust the
volume level or click Mute at the bottom of the panel.
